As a biomaterial a material is called, which is introduced into the bloodstream or industry of the human body, such. As infusion catheters, cardiac catheterization, balloon catheters, was es ist, electrodes, seam material for vascular anastomoses, was es ist, vascular prostheses or support body for vessels, called stents, etc.

Example used under X-ray control usually introduced into the coronary arteries by means of complicated systems catheter stent after expansion of the constricted portion of the artery to the internal splinting of the vessel and remain for this purpose for life in their place. Die Gefährdungen der Patienten, z. The hazards of patients, for. Example by thrombosis and inflammation are known and weighed against the severity of the disease with respect to therapeutic cubital Thrombophlebitis. It is known that bound proteins of the blood plasma, so-called adhesive proteins such as albumin and fibrin, adhesion and aggregation of platelets talk to the biomaterial.

These structures are also was es ist in the adhesion of the platelets on the platelet surface corresponding receptors, cubital Thrombophlebitis. Furthermore, biomaterials, was es ist, the protective cell layers with which the vessels are lined hurt, and the underlying connective tissue such as collagen expose. Auch dort erfolgt dann Adhäsion sowie Aggregation der Thrombozyten. Also, there is then carried adhesion and aggregation of platelets.

As a result of the excessive growth of so-called "smooth muscle" smooth muscle cells can was es ist be concentrated again caused thereby stenoses of blood flow in the vessels. With the implantation of the above-mentioned bodies for support vessels, called stents, blood clotting and inflammation in many patients can be achieved only short-term improvements due to the problems described.

Concomitant systemic treatment of these patients with high doses of anticoagulant drugs called anticoagulants, such as heparin or coumarin derivatives is essential, sometimes combined with medication, called antiplatelet effect the inhibition of platelets.

By this slimy coatings are beyond the bacteria in the body's defenses and neutralize more systemically administered antibiotics: The sensitivity to the bacteria is thus drastically cubital Thrombophlebitis. Mittels intravenöser Antibiotikatherapie können die hohen bakteriziden Konzentrationen nicht immer erreicht werden, da eine Dosiserhöhung häufig aufgrund der Nebenwirkungen cubital Thrombophlebitis ist. By intravenous antibiotic therapy can not be always cubital Thrombophlebitis the high bactericidal concentrations as dose increases are often contraindicated due to side effects.

Nur bei Implantaten aus Biomaterial, die kurzfristig im Körper verweilen, ist durch eine rasche Entfernung des Materials z. Only in implants of biomaterial that linger in the body in the short term, the problem of thrombophlebitis is eliminated by rapid removal of the material for. Dies gilt in der Regel nicht für mittelfristig bzw. This does not apply in the medium or long term implanted was es ist in general. Jede Reimplantation ist jedoch mit Schmerz sowie erneuter Gesundheitsgefährdung belastet.

The above-mentioned and other solutions to the problem of plasma and cellular blood clotting and inflammation hazards relate essentially to the change in the surface charge, the incorporation of anticoagulant drugs in non-resorbable plastics or the cubital Thrombophlebitis of drugs by chemical methods, cubital Thrombophlebitis.

Die Einarbeitung und Fixierung entsprechender Arzneistoffe in eine Kunststoffmatrix brachte jedoch noch nicht die gewünschten Erfolge, da aus den unmittelbaren oberflächennahen Schichten die Arzneistoffe nur kurzfristig und in zu geringen Konzentrationen freigesetzt werden. However, the incorporation and fixing of appropriate drugs in a plastic matrix not yet produced the desired successes because of the immediate near-surface layers, the drugs are released into and to low concentrations only in the short term.

By the release of the incorporated protein adsorption or the effect of chemically bound was es ist is limited or even prevented. This leads to a re-education thrombogenic surfaces associated with the risk of forming blood clots, an excessive formation of new tissue and bacterial colonization. From DE-PS 39 13 a process for producing a textile vascular prosthesis is known. If such textile vascular prostheses are incorporated in the human body, they must be sealed, was es ist, otherwise by the machines of the prosthesis exits the pressurized blood and can lead to significant blood loss.

This sealing is done according to the patent mentioned by coating with cubital Thrombophlebitis absorbable synthetic material through which the entire textile prosthesis is completely surrounded it were a second skin on its periphery. In dieser Patentschrift ist allerdings kein Hinweis auf die Verhinderung von Thrombosen enthalten.

In this patent, however, no reference to the prevention of thrombosis is included, was es ist. Example, is used for the preparation of artificial skin in reconstructive surgery.

Dieses Material besteht Salbe Krampfadern bei A. This material is, for. Example, of polylactide, in which a matrix of polyurethane is applied.

This biodegradable material can be used for the cubital Thrombophlebitis of porous membranes cubital Thrombophlebitis allow large wounds can be covered. Dieses Material wird allerdings nicht dazu verwendet, Biomaterial zu beschichten. This material is however not used to coat biomaterials, was es ist.

Also it should cubital Thrombophlebitis possible, even more, was es ist, eg. This object is achieved according to the invention by the features specified in the characterizing part of claim 1 features.

Example, in tissue or in the blood stream. Decisive is here, that the layer thickness of the degradier- or absorbable coating material are smaller than micrometers, in particular cubital Thrombophlebitis than 50 micrometer or smaller than 10 micrometers.

Die Porosität bleibt somit erhalten. The porosity is thus obtained. Mit einer solchen Beschichtung wird demnach eine poröse Struktur nicht abgedichtet. With such a coating therefore has a porous structure is not sealed, was es ist. In catheters or other biomaterials with a closed surface, only the entire surface is wetted quasi so that only a thin barrier of about 10 microns and less is provided between the biomaterial and the blood or body tissue. Für eine derartige lackartige Beschichtung mit den erwähnten kleinen Schichtdicken können nur resorbierbare Materialien, z.

For such a paint-like coating with the mentioned small layer thicknesses only resorbable materials, was es ist, such. As plastics can be used, which are dissolved, dispersed or emulsified in fast evaporating solvents, so that during the coating results in only a casing of the primary structure of the biomaterial without about the coating flaking off.

Such suitable materials for the coating are known, some are already used within the scope of the delayed release of drugs in the body. To achieve a uniform level of action enterally administered drugs sparingly soluble coatings of capsules, dragees, powders or other galenic forms using gelatin, cellulose, and meth acrylic acid and Fachärzte für Krampfadern derivatives have proven was es ist in addition to other tools in the gastrointestinal tract.

Mit der Entwicklung von im Körper abbaubaren synthetischen Polymeren, die als Arzneistoffträger einsetzbar sind, ergeben sich neue Wege der kontrollierten Freisetzung. With the development of degradable in the body of synthetic polymers that can be used as a drug carrier, new ways of controlled release arise.
